Three Main Air Purifier Types
HEPA (High-Efficiency Particulate Air)
High efficiency HEPA air purifiers effectively capture airborne particles. The percent of particles captured is the highest of any air purification technology available.
Removes up to 99.97% of particles like dust, pollen, pet dander, mold spores and more.
Particles are charged and then stick to oppositely charged metal plates within the air purifier.
Does a poor job at circulating air. Requires frequent cleaning of the plates to maintain efficiency.
Not safe or effective at removing pollutants. By design, they produce ozone, a lung irritant that can cause adverse health effects.
Does not remove particles in the air. Ozone worsens air quality and can cause damage to lungs when inhaled.
Complementary Air Purifier Technology
Effective at removing unpleasant odors, gases, and chemicals in the air. Particles become attracted to, and then trapped within tiny pores in the activated carbon.
Odor, Gases, Chemicals
Helps remove pollen, bacteria, odors, and chemicals. Ionic-only units provide inadequate filtration. Ionizers improve HEPA performance, but don't work well alone.
Pollen, Bacteria, Odor, Chemicals
Molecular Conversion Powder
Destroys tough odors like tobacco smoke at a molecular level, leaving the air smelling fresh and pure.
Smoke, Heavy odor
Silver-infused filters capture and kill airborne microbes. Silver is a natural anti-bacterial.
Microbes, Mold Bacteria, Viruses
Photo-Catalytic Oxidation (PCO)
Destroys gaseous pollutants by converting them into harmless products by the use of UV light and a catalyst (Titanium Oxide).
Captures large particles (hair, large dust particles) to extend the life of your air purifier filter.
Hair, Pet Fur, Large dust particles
Thermodynamic Sterilizing System (TSS)
Destroys 99.9% of living microorganisms and proteins by exposing them to temperatures above 200 C (approx. 400F). Not used with HEPA.
Microbes, Mold, Bacteria, Viruses
Kills airborne germs, bacteria and viruses by damaging the bacteria and viruses' DNA and molecular structure.
